A body of mass `6kg` is under a force which causes displacement in it given by `S= (t^(2))/(4)` maters where `t` is time . The work done by the force in `2` sec is

I was not in sleeping mood but after hearing your voice my situation right now 😴😴😴

🤣🤣🤣

[@shivamkaparwan7976]

Work done is force × displacement why did you use velocity in place of displacement??

[@Ankit-gf4zg]

Actually s=(t^2)/4 is given ds/dt = (2t/4) Therefore, ds = (2t/4)dt Now put the value of ds in workdone formula and put the limits You will get the answer

Please tell that v=2t/4 kasa hua muj ko samaj nahi aaya

[@orggordenofdreams1779]

By differentiation. Consider t² as xⁿ ,use nxⁿ-¹ u will get it
